PE100 Tapping Valve Saddle | Under Clamp | 4mm Auto Pin | Brass Isolation Valve

The electrofusion tapping valve saddle with under clamp adds a new 63mm branch connection with an integral brass isolation valve to an existing PE pipeline — without disrupting the main flow. It combines tapping tee and valve in one fitting, eliminating the need for a separate in-line valve in the service off-take.

The 4mm Fusamatic automatic pin reads the correct welding parameters automatically, ensuring reliable fusion of the saddle to the main pipe. The 14mm AF drive shaft drives the integral cutter through the main pipe wall and then actuates the valve, enabling branches to be made on both dead and live mains.

Manufactured from virgin PE100 black polyethylene with a moulded-in brass sleeve and integrated O-rings for a gas/water tight seal. Rated Water PN16 / Gas 10 Bar. Suitable for gas, water, wastewater, mining and irrigation applications.

Fits main bodies from DN63 to DN225 (SDR 11 – 17.6) with a fixed 63mm outlet — 9 standard references. Operating temperature range: -10°C to +40°C.

• New service connections to existing water and gas mains
• Branching from live mains without shutdown or flow disruption
• Wastewater, mining and irrigation network off-takes
• Where an integral shutoff valve is needed at the point of connection
• Branch points requiring a reusable isolation point

• Integrated brass bodied valve — reusable shutoff point, no additional in-line valve needed (max operating torque 90 Nm)
• 14mm AF drive shaft with integral cutter — cut through the main pipe wall and actuate the valve with one tool (max cutting torque 120 Nm)
• Moulded-in brass sleeve with integrated O-rings — gas/water tight seal for both dead and live mains
• Add branches to existing pipelines without disrupting main flow
• Under clamp snaps quickly into place — saves time, no specialist tooling required
• Fusamatic 4mm automatic pin — reads welding parameters automatically
• Water PN16 / Gas 10 Bar rating (dependent on PE pipe welded)
• Double spigot outlet — ample spigot length to cut off a coupler/reducer and fuse a second fitting
• Saddle and fusion mat designed to minimise joint cycle times
• Rising pin fusion indicator for easy monitoring of the fusion process
• Manual welding parameters moulded into the body as backup
• Permanent batch number + barcode/QR code for full traceability (ISO 13950 / ISO 12176-4)

Note: All stated technical specifications depend on the PE pipe welded to and local pipeline pressure regulations. Please contact us for detailed CAD drawings.
